Study Notes

Blood is considered a tissue composed of different cells working together to transport oxygen, waste products, hormones, and heat from internal organs to plasma.
The four main components of blood are plasma, red blood cells (RBCs), white blood cells (WBCs), and platelets.
Plasma, which is yellow in color, functions to transport cells, hormones, and heat throughout the body and acts as a solvent mainly made up of water.
Red blood cells, produced in red bone marrow, lack a nucleus and are specialized for oxygen transport due to their biconcave shape and the presence of the iron pigment hemoglobin.
White blood cells, produced in bone marrow, come in different types like lymphocytes and monocytes (macrophages), and they play a crucial role in fighting infections by producing antibodies and engulfing pathogens.
Platelets, also produced in bone marrow, are essential for blood clotting to prevent excessive blood loss and the entry of microorganisms.
Blood groups include A, B, AB, and O, and it is crucial for blood transfusions to match these groups to avoid harm to the recipient.
The Rhesus factor is present on the red blood cells of 85% of Irish individuals, influencing compatibility in blood transfusions.
